The phrasal verb "brush down" is typically used in informal contexts, particularly when referring to personal grooming or cleaning tasks. It means to clean or smooth something using a brush, often applied to clothing, hair, or animals. For example, after grooming a horse, one might "brush down" its coat to remove dirt or debris. In human contexts, someone might brush down their jacket or coat to remove dust or lint. Although "brush down" appears in informal situations, such as conversational dialogue, it may occasionally be used in more formal settings like instructional guides or care manuals, especially tying to contexts involving care for animals or maintenance of attire. This phrasal verb is more commonly encountered in British English but is understood in other varieties of English as well. Its use can suggest thoroughness, as "brushing down" implies covering all aspects or surfaces of the item or animal in question.
